possible for, insects to enter the building by Way ,oi `the rabbetyvhen the sash is raised,`were it not aorthe` provision of fthe feature nowfto be de- .scribed, reference being `had to 2. To this 1 i .5ol f The'presence of the rabbet 25 would Ymalte it end there is provided a retractible body, herein a spring 32, within the rabbet 28 and suitably secured, as by a tack 33, to the strip I2. This spring closes the upper end of the rabbet and prevents the entrance of insects when the sash is raised. This will readily be understood by inspection of Fig. l if it be considered that the broken line A-A represents the lower edge of the sash when raised. As shown, the body of the spring is bow shaped and it presents sloping portions above and below its point of engagement with the screen, so that when the latter is raised and lowered the outer end of the rod 28 will ride along the sloping surface of the spring and cause retraction of the same.

The modication shown in Figs. 4 and 5 is precisely the same as that already described, except that instead of employing a screw threaded rod there is a rod 34 which is spring mounted, this being conveniently accomplished in the present example by making the rod as a part of a piece of spring wire bent to provide a spur 35 driven into the screen frame and a resilient portion 36 which normally overlies the inner face of the guide rail I6. By grasping the inner end of the rod Aand pulling the same inwardly a sufficient extent to enable the overlying portion to be retracted inwardly, the screen frame may be detached from the guide rail I0 in the same manner as that already described in connection with the rst form of the invention.

Having thus described two embodiments of the invention, but without limiting myself thereto,

Awhat I claim and desire by Letters Patent to secure 1. A window screen having a frame comprising opposite, vertical members guidable on guide rails, one of said members having a surface to overlie one face of an associated guide rail, and a retractible body carried by said screen and overlying the opposite face of the associated guide rail.

In a window screen, the combination of a vframe comprising two members for engagement Y with opposite guide rails of a window, one member carrying a projection to overlie one face of the guide rail therefor, and a body carried by said screen and having a resilient portion to overlie the opposite face of such guide rail, said body having a spur portion driven into said screen, and

a portion which may be manipulated to ex and retract said resilient portion inwardly with relation to theadjacent edge of said screen. l

18. In a window screen, the combination of a Trame comprising two members for engagementV with opposite guide rails of a window, one member carrying a projection to overlie one face of the guide rail therefor, and a body carried by said screen and having a resilient portion to overlie the opposite face of such guide rail, said body having a spur portion driven into said screen, and va portion which extends through a portion of said screen and may be manipulated to ex and retract said resilient portion inwardly with relation to the adjacent edge of said screen. v
